Hottest day in recorded history in the UK today (37.9°C at Heathrow). In Birmingham, sudden deluge and seriously sinuous forked lightning over the village pub where we were having lunch. The electricity cut out, candlelight at 2pm under the darkness of the storm. Fourteen people injured from a lightning strike at a football match in Birmingham, others elsewhere. On the train back to London, more lightning at Northampton. Hoping the storm makes it to London before we do, to cool things down. Peter Weir’s The Last Wave feels like required viewing when we get home.
